    Chapter 20 Assessment of radiation pollution from nuclear power plants

    Nuclear power plants split uranium atoms in a process called fission. In a nuclear power plant, heat is generated to produce steam that spins a turbine to generate electricity. Nuclear energy has been proposed in response to the need for a clean energy source compared to CO2 production plants. However, nuclear energy is not necessarily a source of clean energy as nuclear power plants release small amounts of greenhouse emissions in activities related to building and running the plant. Moreover, even if all safety measures are followed, there is no guarantee that an accident will not occur in a nuclear power plant. In the case of an accident involving a nuclear power plant, the environment and the people around it may be exposed to high levels of radiation. Another important environmental problem related to nuclear energy is the generation of radioactive waste that can remain radioactive and dangerous to human health for thousands of years. There are also several issues with burying the radioactive waste. Here, we describe different types of radioactive waste pollution from nuclear power plants, their environmental effects, nuclear regulations, and nuclear power plant incidents. Moreover, two case studies on nuclear power plant accidents and their consequences are discussed

    The tobacco industry’s challenges to standardised packaging : A comparative analysis of issue framing in public relations campaigns in four countries

    Tobacco industry public relations campaigns have played a key role in challenges to standardised cigarette packaging. This paper presents a comparative analysis of industry campaigns in Australia and the United Kingdom, which have implemented standardised packaging legislation; Canada, where policy has been adopted but not yet implemented; and the Netherlands, which has considered, but not enacted regulation. Campaigns were identified via Google searches, tobacco industry websites, media coverage, government submissions and previous research; analysis focused on issue framing and supporting evidence. Public relations campaigns in all case study countries drew on similar frames - the illicit trade in tobacco products, the encroaching 'nanny state', lack of evidence for the effectiveness of standardised packaging, a slippery slope of regulation, and inherent threats to intellectual property rights. These claims were supported by industry research, front groups and commissioned reports by accountancy firms, but were not with verifiable research. Independent evidence that contradicted industry positions was overlooked. Similarities in structure and content of public relations campaigns in countries that have enacted or considered regulation points to a strategic co-ordinated approach by cigarette manufacturers. Countries considering standardised packaging policy can expect powerful opposition from the tobacco industry. Tobacco control communities and policy makers can learn from previous experience, and share best practise in countering industry arguments

    GMOs in animal agriculture: time to consider both costs and benefits in regulatory evaluations

    In 2012, genetically engineered (GE) crops were grown by 17.3 million farmers on over 170 million hectares. Over 70% of harvested GE biomass is fed to food producing animals, making them the major consumers of GE crops for the past 15 plus years. Prior to commercialization, GE crops go through an extensive regulatory evaluation. Over one hundred regulatory submissions have shown compositional equivalence, and comparable levels of safety, between GE crops and their conventional counterparts. One component of regulatory compliance is whole GE food/feed animal feeding studies. Both regulatory studies and independent peer-reviewed studies have shown that GE crops can be safely used in animal feed, and rDNA fragments have never been detected in products (e.g. milk, meat, eggs) derived from animals that consumed GE feed. Despite the fact that the scientific weight of evidence from these hundreds of studies have not revealed unique risks associated with GE feed, some groups are calling for more animal feeding studies, including long-term rodent studies and studies in target livestock species for the approval of GE crops. It is an opportune time to review the results of such studies as have been done to date to evaluate the value of the additional information obtained. Requiring long-term and target animal feeding studies would sharply increase regulatory compliance costs and prolong the regulatory process associated with the commercialization of GE crops. Such costs may impede the development of feed crops with enhanced nutritional characteristics and durability, particularly in the local varieties in small and poor developing countries. More generally it is time for regulatory evaluations to more explicitly consider both the reasonable and unique risks and benefits associated with the use of both GE plants and animals in agricultural systems, and weigh them against those associated with existing systems, and those of regulatory inaction. This would represent a shift away from a GE evaluation process that currently focuses only on risk assessment and identifying ever diminishing marginal hazards, to a regulatory approach that more objectively evaluates and communicates the likely impact of approving a new GE plant or animal on agricultural production systems
